Paint pollutants and their harmfulness
1、主要污染物： a、漆雾； b、挥发性有机废气
1. Main pollutants: A, lacquer mist, B and volatile organic compounds.
2, the formation and harmfulness of pollutants:
A, paint fog: liquid paint atomized dust particles formed under the action of air pressure, sticky, easy to adsorb on the contact of people or objects, and is a potential carcinogen, causing pollution to the whole atmosphere.
B, volatile organic waste gas: organic solvent, mainly three benzene (benzene, toluene, xylene) is used to dilute the paint to achieve the smooth and beautiful surface of the surface of the object, but the organic solvent is volatile and can not be attached to the surface of the object with the paint for a long time. The organic solvent will be completely released in the spraying and drying process, thus forming organic matter. Exhaust gas, which is colorless and irritant, spreads in the atmosphere with the flow of air. It can cause injury to the human respiratory system, blood, heart, lung, liver, mucous membrane, eyes, and nerve through human respiration or direct action to the human body, and can also directly harm people through the skin.
